A contract [u]has[/u] to stipulate working hours, but to those questioning them: I don't think you really get it.Being a consultant is a delivery focused job, you are not really paid to be there 9-5 (or whatever) and turn a handle, you are there to create positive outcomes, be they winning a bid, or fulfilling client expectations.A 'good' consultant will do whatever it takes to get the job done, and it is the outputs on which you should be measured. In a typical Big 4 'round table', your rating will not be based on the hours you worked, nor should they be. Rather, you will be assessed on the strength of your delivery, and the outcomes of your delivery.This is a fundemental part of our jobs, and if you don't like it, one could argue that consulting is just not the right career for you.(I'm an ex-Big 4 manager, now at a niche consultancy, and my words above are a whole-market assumption - they don't (and shouldn't) differ according to which firm you happen to work for).
